Patent number: 7998130Abstract: A system for connecting a compatibility liner with a source of perishable therapeutic is provided. In one exemplary system for connecting a reservoir of perishable therapeutic with a lumen, a hollow hub having a first end and a second end is provided. The first end of the hollow hub, which contains a bond port, is in fluid communication with the second end. The second end of the hollow hub may contain a docking groove that is sized to couple a reservoir to it. The system also includes an inner hypo-tube having a proximal tip and an inner lumen. This inner lumen is lined with a therapeutic compatible lining and is in fluid communication with the second end of the hub through the proximal tip of the inner hypo-tube. The inner lining and the proximal tip in this system are configured to shield therapeutic ejected from the reservoir from contacting materials that can diminish the integrity of the therapeutic.Type: GrantFiled: February 13, 2008Date of Patent: August 16, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Justin Crank, Timothy Ostroot

Publication number: 20050261667Abstract: Devices and methods for performing improved percutaneous myocardial revascularization (PMR) procedures. One device includes a preassembled PMR drug delivery catheter and a drug neutralizing vial. The vial assembly allows prepping the PMR catheter by flushing drug through distal needle, and into a vial cavity where the drug is neutralized by a neutralizing agent. One set of devices includes needles having protrusions secured to the distal regions of drug delivery tubes. One needle has outward protruding barbs engaging the inner tube wall while another needle has outward threads which can screw into the tube inner wall. Radiopaque marker bands are also included in the present invention which are asymmetrically distributed on the catheter shaft, allowing a treating physician to determine under fluoroscopy whether the catheter distal region is pointed away or toward the treating physician, as well as determining whether the catheter distal region is rotated toward or away from the treating physician.Type: ApplicationFiled: July 28, 2005Publication date: November 24, 2005Inventors: Justin Crank, Scott Larson, Timothy Mickley
